Answer 1

Answer: (A)

Sequential access

Sequential access methods are used in accessing sequential files. Sequential access is an access to a computer data file that requires the user to read through the file from the beginning in the order in which it is stored.

The sequential file is a file that contains records or other elements that are stored in a chronological order based on account number or some other identifying data. Sequential files must be read starting at the beginning of the file.
